out of interest, whats the general ratio of guys becoming teachers to women becoming teachers these days?
I can't remember the exact figures off the top of my head, but there are still more females in teacher training courses than guys. It changes for stages too, in early education there are barely any guys, but it goes up a little in primary and more again in secondary teacher training courses. Females are still far more greatly represented than guys though, in my specialisation there will be 3 guys graduating compared to 15-18 women.
As the others have said about teaching in Japan, there are stacks of opportunities and agencies out there to help you, so there's no real worries there. Some are just after a degree and you'll teach English, others will require you to have a teaching degree of some nature.
Saying that, there are many many recruiters and agencies for international teaching, from Japan to the UK to South Africa to the Middle East. Just looking at one recruiter I get contacts from, there's a current job for an ICT Teacher in Oman, an Early Years teacher in Japan - these sort of jobs require an education degree.
